OH-group-containing moleculesThe formation of (M-H) ions from OH-containing benzene derivatives, covering azobenzenes and phenols, has been investigated by resonant electron-capture mass spectrometry. A vibrational fine structure in the effective ion yield curves, at threshold energies for the ...
Structure and Mode-of-Action of the Two-Peptide (Class-IIb) Bacteriocins group of ions, indicating that the bacteriocins form or induce the formation of pores that display specificity with respect to the transport of molecules. ... Jon,Nissen-Meyer,Camilla,... - 《Probiotics & Antimicrobial Pr...
A crystallization pathway describes the movement of ions from their source to the final product. Cells are intimately involved in biological crystallizatio... S Weiner,L Addadi - 《Annual Review of Materials Research》 被引量: 290发表: 2011年 A satellite-based assessment of transpacific transport...
We have determined enthalpies of formation for acetaldehyde, propanal, and butanal from thermodynamic cycles, using experimentally measured reaction and formation enthalpies. All enthalpy values used for reference molecules and reactions were first verified to be accurate to within around 1 kcal mol-1 ...
electronic state for the first negative system of N+2 emitted in the afterglow of a helium-nitrogenmixture, is measured by photography. This distribution has been compared with that obtainedby collision between metastable xenon atoms with normal CO molecules giving excited neu-tral CO molecules. The...
Determining enthalpies of formation from equilibrium constants Negative ions VO-2, VO-3, V2O-5, V3O-8, and V4O-10 were found in the vapors of vanadium oxide at temperatures T = 1200 K to 1500 K. Equilibrium constants o... B E.,Rudnyi,and,... - 《Journal of Chemical Thermodynamics...
The invention relates to a process of generating N(CF3)2 anions by reacting a metal fluoride of formula MFx with a compound of formula RFSO2N(CF3)2, (CF3)2N(SO2CF2)mSO2N(CF3)2 or RFCON(CF3)2. The invention further relates to the use of the N(CF3)2 anions as a reagent for...
There are certain differences in the reactivity of chlorinating agents. In particular, the most popular sodium hypochlorite and molecular chlorine (chlorine water) exist in aqueous solution in the form of mixtures of molecules and ions due to equilibrium reactions with water. Gaseous chlorine in wate...
The interaction between nitrogen monoxide (NO) and organic peroxy radicals (RO2) greatly impacts the formation of highly oxygenated organic molecules (HOM), the key precursors of secondary organic aerosols. It has been thought that HOM production can be
We report here the first results of a study of the enzymatic formation of halogenated C1/C2-hydrocarbons from natural, biochemically relevant molecules using enzymes such as chloroperoxidase (CPO) or horseradish peroxidase (HRP). As halogen sources KBr, NaCl or a sea salt solution were utilized...
